Openqdb

What it is

Openqdb is a piece of software written in PHP 4 which uses a MySQL database
to store user-submitted quotes. Anyone can vote on these quotes to rate
how good they are and those with a special moderator account can allow or
reject submissions and edit them. For those who are familiar with the sites
bash.org or
qdb.us, Openqdb is a reimplementation of them
for anyone to use and start their own site.

Why it is

But you'll hear a lot of "should have" and "could have been" with bash.org.
It is no secret that the management has been — for easily over a year
— deliberately prohibiting the betterment of the site and features.
It's harsh to say and some would claim "bullshit" on that fact, but it would
have been extremely trivial for the management to develop new features and a
better site, should they have had the desire.

While bash and QDB are OK at what they do, their management is at best
dubious. Even the bash.org moderators are fed up with the behaviour of the
administration, and it's often been observed that many amusing quotes are
rejected while transparent clichés are accepted.

Besides, in the event that bash or QDB goes down, quotes may well be lost
permanently as they are centralised repositories and not many people bother
to keep backups of them. It's more reliable overall if people run their
own quote sites. Those who run bash.org/QDB have not felt a need to make the
source code running bash.org open source.

Releasing public domain software to enable people to setup their own sites
can only be a good thing.
